Echotel® Sanitary
Model 960/961
Ultrasonic Level Switches
|
The Echotel Model 960/961 switches are designed for the stringent requirements of hygienic applications. These switches are offered with a deep-drawn 304 stainless steel housing that is desireable for CIP and SIP procedures. A 20 Ra surface finish is featured with sanitary Model 960/961 transducers. These transducers are available with 1"/1 1/2" & 2".
Echotel Model 960/961 Ultrasonic Level Switches use pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference. Extensive self-testing of the electronics and transducer make this advanced switch suitable for a wide variety of sanitary level switch applications.

- 20 Ra surface finish with Tri-Clamp® and Varivent® flanges
- Adjustable time delay for turbulent aerated liquids
- Tip-sensitive transducer measures level within 1/4" of the vessel bottom
- Pulsed signal technology provides superior performance in difficult process conditions
Applications:
- Mixing and blending vessels
- DI/WFI applications
- Solvent storage
- Biowaste tanks
- Sterile liquid media tanks
- CIP buffer tanks
Options:
- Actutator-Sensor-Interface (AS-i), relay or current shift electronics
- Glass window cover
- Deep drawn 304 stainless steel or cast aluminum housings
